Problems solved by technology

In fact, the structures of the objects obtained by this known device are usually not very compact and they have clear burrs whose removal requires expensive finishing operations
Basically, this known device needs to be stopped only after a few machining cycles in order to then be able to start again after the preparation step, which is unacceptable in the normal operation of the device in an industrial production process

Embodiment Construction

[0017] With reference to the drawings, the device according to the invention for the manufacture of articles of light alloy or similar material comprises a mold, indicated in its entirety by the reference numeral 10 . Purely by way of example, the apparatus shown in the figures will manufacture multiple toe caps for safety shoes in a single molding operation.

[0018] The mold 10 comprises a lower mold half 12 and an upper mold half 14 , both metallic, capable of being joined together in the closed configuration of the mold 10 .

[0019] In particular, the lower mold half 12 will be detachably fixed on a support plane determined by a press (not shown in the figures, since it is of a known type per se) which enables the upper mold half 14 to be placed on the mold 10. The vertical movement during the closing and opening steps of the mold simultaneously applies pressure to the two halves of the mold.

[0020] The lower half-mold 12 is passed at a substantially central position b...

Abstract

The application discloses a device for the manufacture of objects of light alloy or similar material comprising a mold (10) comprising two mold halves (12, 14) capable of being joined together, namely a lower mold half and an upper mold half . The lower mold half (12) defines a molding cavity (20) adjacent to a supply duct (16) for the liquid metal which passes through the lower mold half to the liquid metal in the molding cavity (20). Introduce channel (18). The upper mold half (14) is connected to at least one movable punch (24) provided with a molding surface (21) which together with the molding cavity (20) defines the The shape of the item. Each punch (24) performs the function of a ram in order to stop the flow of liquid metal towards the molding cavity (20). The device comprises a temperature control device and a temperature sensor connected to a control unit (32) which prevents the movement of the movable punch (24) when the temperature of the mold halves (12, 14) is not within a predetermined range of values.

Description

technical field [0001] The present invention generally relates to devices for the manufacture of objects of light alloys, such as aluminum alloys, aluminum alloys and the like. Background technique [0002] EP-1472027 describes such a device, which performs a "liquid metal forging" process, also known as "squeeze casting". This known device basically comprises a lower mold half, which can be connected together, and at least one upper mold half, the lower mold half being passed through by a liquid metal introduction duct, which is connected to the Below the metal melting furnace connection. In the lower mold half, at least one lower cavity is defined near the edge of the liquid metal introduction conduit, the lower cavity having a concave portion that will receive a quantity of liquid metal that is supplied through said conduit, And dose by spilling from the edge of the catheter. The upper mold half is associated with at least one movable punch movable relative to the two ...
